   acid      calcium      chloride      copper      hydrochloric      hydrogen      iron      magnesium      salt      sulfate      sulfuric      zinc   
1. Metals react with acids to form a solution of a and gas is given off.
2. Complete the following word equations:
(a) + ==> iron chloride + hydrogen
(b) zinc + sulfuric acid ==> +
(c) calcium + hydrochloric acid ==> +
(d) + ==> magnesium sulfate + hydrogen
3. The following observations were made by a student when small quantities of the metals were added to dilute hydrochloric acid
ironslow bubbling
magnesiumlots of bubbles, heats up
copperno bubbles at all?
zincquite rapid bubbling, maybe heated up?

From these observations, work out the reactivity order
Most reactive: :Least reactive
